So I will start off by stating I have moved the regular install location of Oracle 11.2 XE to a logical volume (/oracle) I had created on my RHEL 6.6 server. After shutting down both the database and the Oracle listener, I performed...
$ cp -R /u01/app/* /oracle
$ rm -rf /u01/app/oracl
$ ln -s /oracle/oracle /u01/app/oracle
Then restarted the listener and the database. Now when I attempt to run the following as the user 'oracle' I get a message...
$ sqlplus
Enter user-name: sys / as sysdba
Enter password: ****
Connected to idle instance.
Further, when I attempt a startup I get an error.
> startup
ORA-45301: XE Edition single instance violation error
I have attempted the solutions found here to no avail.
Here is the output for my listener controller:
bash-4.1$ lsnrctl status

The command completed successfully
I'm really quite lost as to what to attempt next. I know I could just reinstall and keep the directory in its proper location but I need it to be in it's own logical volume.
EDIT
Some further information to help clarify my system...
bash-4.1$ env | grep ORA
ORACLE_SID=XE
ORACLE_BASE=/oracle/oracle
ORACLE_HOME=/oracle/oracle/product/11.2.0/xe
bash-4.1$ env | grep TNS

FURTHER EDIT
Attempting to sign in to sqlplus using the SYSTEM user returned an error:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
FURTHER EDIT
Output of the ipcs command

Issue was a wrong entry in tsnnames.ora (I had added a line that shouldn't of been there) and as well the permissions for my /oracle directory were incorrect. Thank you to everyone who tried to help, it was greatly appreciated.
